This appears to be an Australian model and these are the only spares I can find. They do sell the latches. If the hinges are damaged and causing this, you will feel movement. Looks like it is time for a new one.
It sounds like one of the door switches has become defective, each must be disconnected on the one side and tested with a digital meter using the ohms scale.
At
our Web site, we have a video available
showing how to remove a typical over the range control panel assembly in under 5
minutes.
Then you can get to the switches.
Or it may be a sticking relay on the control board. We
regularly repair these control units for customers nationwide by
mail for $39.95 postpaid in about a week or so with a one-year
guarantee.
If during this unwanted operation the oven lamp, internal cooling fan, and stirrer are all stuck on, but the turntable is not on moving and the oven is not actually cooking, then I would suspect relay RY1 on the control board is stuck.
i just checked my R-3A36 manual to find out the wattage. it's 800 watts. i make pralines in my microwave. i am always asked for the recipe. so i needed to be able to tell people the wattage of my oven so they can adjust the recipe to their oven.
garry, metairie,la.
You need to know where the 'catches' are inside the choke cover on the door to remove it carefully without breaking anything or marring the cover. You might get inside and find that the post for mounting the return spring has broken and that is part of the outer door panel.
